Additional info: This tracker bug is not a tracker just for known issues (like it was the last releases) but for every change that should appear in the Release Notes - major updates, technical previews, deprecated functions, and so on.
If there is a change that does not have a separate bug (for example it is a change introduced in a rebase), add that rebase bug as a blocker and specify the nature of the change in the doc text field of that bug.
